7.1 系统上电，预热15分钟左右。按负荷清零，按一下标定键，观察标定值是否为计量标定值（每年年检时确定的值），否则需进行调整，使显示值与计量标定值相一致。再按一下标定键。
7.1 The system is powered on and preheated for about 15 minutes. According to the load clearing, press the calibration key to observe whether the calibration value is the calibration value of measurement (the value determined at the annual inspection), otherwise it needs to be adjusted to make the display value consistent with the calibration value of measurement. Press the calibration key again.
7.2 操作操作面板上的“上升”或“下降”及“停止”按键调整移动横梁到合适的位置。注意：操作完“上升”键，必须按“停止”键后，才能再按“下降”键，反之依然。
7.2 Operate the "up" or "down" and "stop" buttons on the operation panel to adjust the moving beam to the appropriate position. Note: After the operation of the "up" key, you must press the "stop" key before pressing the "down" key, and vice versa.
7.3将试样夹持在辅具上，上端固定牢靠，按动负荷清零键，再固定好下端，选定档位，再选定速度。
7.3 Hold the sample on the auxiliary tool, fix the upper part firmly, press the dynamic load clearing key, beijing.89ix.com zhixiang.07858.netdianxiangan.37ix.cn zhoucheng.37ix.cn chongdianzhuang.07858.net langyashan.37ix.com.cnfix the lower part, select the gear, and then select the speed.
7.4 按动“开始”键，即开始试验，试验力到达1000N横梁将自动停止。有时需迅速按下“停止”键移动横梁方能停止移动。
7.4 Press the "Start" key, that is, start the test, the test force reaches 1000N beam will automatically stop. Sometimes it is necessary to press the "stop" button quickly to move the beam in order to stop moving.
7.5 重复7.2、7.3、7.4，继续下面的试验。
7.5 Repeat 7.2, 7.3, 7.4 and continue the following experiment.
7.6 按F3键打印试验数据。
7.6 Press F3 to print test data.
